usb keyboard not working
Hi,
I recently bought a Zalman ZM-K400G keyboard, well, it's a cheap product but it was working fine until I replaced my mobo and cpu and reinstalled windows. Now it sometimes works normal, sometimes works but not during boot (so I can't enter bios settings) and sometimes doesn't work at all.
When it doesn't work at all, Windows device manager sees it as an unknown device and no troubleshooting, uninstalling and reinstalling drivers etc does anything... It looks completely dead; only when I insist on pushing some of the keys its lights faintly glows momentarily (but no effect, it doesn't write anything)...
When I reinstalled windows and then tried to install the mobo drivers, I experienced weird problems (keyboard and mouse didn't work etc.) so I'm still not sure if I installed the drivers or not. (I always have an "unknown device" exclamation on my PC device on "devices and printers" window.)
